In the aftermath of World War II, the US government extracted Nazi scientists from Germany through Operation Paperclip. This led to the formation of Project MK ULTRA, a secret CIA project that involved conducting inhumane experiments on innocent citizens, including drug use, rape, torture, and murder, on a massive scale spanning decades. The project was allegedly shut down after being discovered, but not before the CIA destroyed thousands of documents to conceal their illegal activities.
